Senior Security Engineer (2019 to current)

With the lateral move as architect at the product engineering department to the internal security department, I was able to apply much of the same principals of standardization and automation to Leaseweb’s internal office network. The internal network suffered from the rapid growth of the company and felt like the right challenge.

ByteSheep Services

Owner (2015 to current)

ByteSheep Services is my own company. Started from the typical “can you host my website” friends and family service. My passion for radio quickly added streaming as a new service. With the trials of DAB+ broadcasting in the Netherlands I have teamed up with RF experts to form DAB Partners. Where I provide DAB+ supporting services such as streaming, trans-coding, multiplexing, content delivery and transmission line monitoring. As well as supporting on-site installation of the equipment, network and wireless transmission equipment.

Co-Owner (2014 to current)

Branching off the photography hobby, together with a fellow photographer, who was already doing timelapses at Bevrijdingspop, we gave it a live twist. Our service provides a high quality timelapse with the latest live image and periodically generated video accessible per API. To provide this, we build custom hardware to control the DSLR coupled with an API to ingest and process the images. The delivery is done trough a scalable CDN.

ZFM Zandvoort

A local radio station is a combination of mostly analog audio equipment and a digital backbone. Combining this with the transmission equipment, there is a broad spectrum of technologies to be maintained. We also develop custom hardware as needed.

Broadcasting is also performed in external locations, introducing p2p audio transmissions and mobile studios.

Ground Control Show

Stage Technician 2008

Working in a small team, you are self sufficient and responsible for transport, setup and operation of all equipment that is needed at a particular show. The contracts varied from small garden events to Mystery Land and Rockit Open Air. Setups including Sound, Light and Rigging. The irregular working hours, troubleshooting on demand (with the tools and people at hand) and variety of venues still intrigue me today.

Graphical Design (Internship) 2006
